[PDF][PDF] Impaired DNA damage response, genome instability, and tumorigenesis in SIRT1 mutant mice

RH Wang, K Sengupta, C Li, HS Kim, L Cao, C Xiao… - Cancer cell, 2008 - cell.com
In lower eukaryotes, Sir2 serves as a histone deacetylase and is implicated in chromatin
silencing, longevity, and genome stability. Here we mutated the Sirt1 gene, a homolog of yeast …

Positional stability of single double-strand breaks in mammalian cells

E Soutoglou, JF Dorn, K Sengupta, M Jasin… - Nature cell …, 2007 - nature.com
Formation of cancerous translocations requires the illegitimate joining of chromosomes
containing double-strand breaks (DSBs). It is unknown how broken chromosome ends find their …

[HTML][HTML] Lamin A/C and Emerin depletion impacts chromatin organization and dynamics in the interphase nucleus

…, M Jayakrishnan, S Hegde, K Sengupta - BMC Molecular and Cell …, 2019 - Springer
Background Nuclear lamins are type V intermediate filament proteins that maintain nuclear
structure and function. Furthermore, Emerin - an interactor of Lamin A/C, facilitates crosstalk …

Nuclear envelope protein lamin B receptor protects the genome from chromosomal instability and tumorigenesis

S Patil, S Deshpande, K Sengupta - Human Molecular Genetics, 2023 - academic.oup.com
Lamin B Receptor (LBR) is an inner nuclear membrane protein that assembles the nuclear
envelope post mitosis. Here we show that LBR depletion induces mitotic defects …

Studying the role of chromosomal instability (CIN) in GI cancers using patient-derived organoids

S Patil, S Jahagirdar, M Khot, K Sengupta - Journal of Molecular Biology, 2022 - Elsevier
Chromosomal instability (CIN) is associated with the initiation and progression of
gastrointestinal (GI) tract cancers. Cancers of the GI tract are typically characterized by altered …

Role of A‐and B‐type lamins in nuclear structure–function relationships

S Patil, K Sengupta - Biology of the Cell, 2021 - Wiley Online Library
Nuclear lamins are type V intermediate filament proteins that form a filamentous meshwork
beneath the inner nuclear membrane. Additionally, a sub‐population of A‐ and B‐type lamins …

[HTML][HTML] HOXA repression is mediated by nucleoporin Nup93 assisted by its interactors Nup188 and Nup205

AS Labade, K Karmodiya, K Sengupta - Epigenetics & chromatin, 2016 - Springer
Background The nuclear pore complex (NPC) mediates nuclear transport of RNA and proteins
into and out of the nucleus. Certain nucleoporins have additional functions in chromatin …

Lamin B2 modulates nucleolar morphology, dynamics, and function

A Sen Gupta, K Sengupta - Molecular and cellular biology, 2017 - Taylor & Francis
The nucleolus is required for ribosome biogenesis. Human cells have 2 or 3 nucleoli associated
with nucleolar organizer region (NOR)-bearing chromosomes. An increase in number …

INDQ/NO, a bioreductively activated nitric oxide prodrug

K Sharma, A Iyer, K Sengupta, H Chakrapani - Organic letters, 2013 - ACS Publications
The design, synthesis, and development of INDQ/NO, a novel nitric oxide (NO) prodrug
targeted by a bioreductive trigger, are described. INDQ/NO, an indolequinone-diazeniumdiolate …

Direct demonstration of seed size-dependent α-synuclein amyloid amplification

…, D Chatterjee, J Devi, K Sengupta… - The journal of …, 2022 - ACS Publications
The size of amyloid seeds is known to modulate their autocatalytic amplification and cellular
toxicity. However, the seed size-dependent secondary nucleation mechanism, toxicity, and …
